Wireless parameters are the settings and configurations that characterize a wireless network (RAN) and play a critical role in determining network performance, coverage and overall functionality. These parameters are critical to delivering the desired user experience, meeting service demands, and ensuring efficient network operation; and the basic wireless parameters in 5G(NR) include the following:
1、 Frequency bands (Sub 6GHz and mmWave):5G can operate in Sub6 GHz and mmWave (millimeter wave) frequency bands, where Sub 6GHz provides wider coverage, while mmWave provides higher data rates but shorter coverage.
2、Parameter Set:It defines parameters such as subcarrier spacing and symbol duration in 5G, which allows flexibility to accommodate a variety of use cases with different latency and throughput requirements.
3、Modulation and Coding:Higher-order modulation schemes such as 256QAM can be used in 5G systems to increase data rates. Adaptive modulation and coding can be dynamically adjusted according to channel conditions to optimize data rates while maintaining reliability.
4、Duplexing Scheme:5G supports full-duplex TDD and FDD communications, which means that it allows simultaneous transmission and reception on the same frequency, and also supports half-duplex configurations for communications in one direction at a time.
5、 Structure Frame: 5G is flexible in time slot and symbol configuration, where flexibility is provided in the time slot and symbol configuration of the frame structure to accommodate a variety of use cases, including low latency and high throughput scenarios.
6、Channel Coding and Error Correction: 5G employs advanced channel coding techniques to enhance error correction and ensure reliable communications even under challenging radio conditions.
7、Multiple Antenna Technologies: 5G networks utilize Mass MIMO (Multiple Input Multiple Output) and Beam Forming to enhance coverage, capacity and overall network efficiency.
8、TimeSlot Format: 5G introduces a variety of time slot formats, including normal time slots, short time slots, and mini time slots, to accommodate different traffic characteristics and delay requirements.
9、Frequency Guidance and Reference Signals: 5G combines frequency guidance and probe reference signals to assist in channel estimation for efficient beamforming and network optimization.
10、TTI (Transmission Time Interval): Defines the time interval between transmissions in the air interface. Configurable TTI allows optimization for different services and use cases.
11、Beam Management: 5G includes parameters related to beamforming that enable efficient beam management, concentrating signals in specific directions to improve signal strength and overall network coverage.
12、Switching Thresholds and Triggers: Defines thresholds and triggers for initiating switching between different cells or base stations to ensure seamless mobility of connected devices.
13、Slicing Configuration Parameters: 5G parameters in the context of network slicing include the configuration of different network slices, each of which is customized according to specific service requirements and characteristics.
14、Authentication and Encryption: Settings Security parameters include settings related to user authentication, encryption, and integrity protection to ensure confidentiality and integrity of communications.
15、SBA Architecture: With the transition to a service-based architecture, parameters related to service provisioning, orchestration, and management play a vital role in providing flexible and efficient services.
16、Quality of Service QoS parameters: include settings used to prioritize different types of traffic, ensuring that critical applications receive the necessary resources and meet specific performance criteria.
17、Carrier Aggregation :defines how multiple frequency bands are aggregated to increase overall network capacity and data rates.
18、Interference Management: Parameters related to interference management include configurations to mitigate interference from adjacent cells or frequency bands and optimize overall network performance.
